hipify-clang

hipify-clang is a clang-based tool to automatically translate CUDA source code into portable HIP C++.

Table of Contents

Build and install

Dependencies

hipify-clang requires clang+llvm of at least version 3.8.

In most cases, you can get a suitable version of clang+llvm with your package manager.

Failing that, you can download a release archive, extract it somewhere, and set CMAKE_PREFIX_PATH so cmake can find it.

Build

Assuming this repository is at ./HIP:

mkdir build inst

cd build
cmake \
 -DCMAKE_INSTALL_PREFIX=../inst \
 -DCMAKE_BUILD_TYPE=Release \
 -DBUILD_HIPIFY_CLANG=ON \
 ../HIP

make -j install

The binary can then be found at ./inst/bin/hipify-clang.

Test

hipify-clang has unit tests using LLVM lit/FileCheck.

To run it:

  1. Ensure lit and FileCheck are installed - these are distributed with LLVM.
  2. Ensure socat is installed - your distro almost certainly has a package for this.
  3. Build with the HIPIFY_CLANG_TESTS option turned on.
  4. make test-hipify

Running and using hipify-clang

To process a file, hipify-clang needs access to the same headers that would be needed to compile it with clang.

For example:

hipify-clang square.cu -- \
  -x cuda \
  --cuda-path=/opt/cuda \
  --cuda-gpu-arch=sm_30 \
  -isystem /opt/cuda/samples/common/inc

hipify-clang arguments are given first, followed by a separator, and then the arguments you'd pass to clang if you were compiling the input file. The Clang manual for compiling CUDA may be useful.

For a list of hipify-clang options, run hipify-clang --help.
